A federal appeals court says U.S. wildlife officials did not consider all environmental factors when it decided against designating a Montana fish as a threatened or endangered species.

A three-judge panel of the 9th U.S. Circuit Court of Appeals Friday sent a lawsuit seeking federal protections for the Arctic grayling back to a lower court for further consideration.

Starting next week Yellowstone National Park staff will begin chemically treating the upper Gibbon River, continuing a project to remove nonnative fish in central Yellowstone.

Algae growth is increasing on Montana’s famed Smith River and scientists don’t know why. So, they’re turning to the public for help.

Excessive algae can deplete oxygen and alter water pH levels, harming fish and other aquatic life in the process. Algae blooms are also a nuisance to humans who encounter them on rivers and lakes.

'Field Notes:' What's Wrong With Whitefish?

I dipped my woven landing net into the frigid creek water and drew the fish towards my legs. It was winter and I was standing mid-calf deep in a favorite fishing spot outside Missoula. I knew the fish wasn’t a trout before I scooped it into my net.

An icy bank embraced the creek, and my breath rose before me, rhythmically billowing out my mouth and nostrils. The fish nonchalantly took one of the nymphs I had been sinking near the creek bottom, diving into the depths and pulling its weight into my fly line. I could feel its tail in the handle of my fly-rod, palpitating like an irregular heartbeat.

Biologists with Montana Fish Wildlife & Parks have traced the origin of two illegally introduced walleye discovered in Swan Lake.

FWP announced Tuesday that researchers traced the fish back to Lake Helena by looking at their otoliths, or inner ear bones.
